Electronic leak detection for homes and businesses in Lower Kingswood
We carry out electronic leak detection on flat roofs in Lower Kingswood and across London and the South East. Testing usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. You get a photo-illustrated written report. We are often asked to look into breaches hidden under paving or planting and leaks showing away from the breach, across flat roof membranes, commercial flat roofs and single-ply roofs.
In a small place like Lower Kingswood, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Signs you need electronic leak detection in Lower Kingswood
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
Here are some of the things we see often:
- Leaks at pipes, outlets or fixings
- Holes left by work on the roof
- Stains far from any visible defect
- Leaks through a covered membrane
Take an older house close to Church of Jesus Christ and the Wisdom of God: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Questions to ask before booking
- How they plan to inspect the roof safely
- Will they check the loft as well as the outside?
- How soon the report will arrive
- What exactly goes into their report
What we look for on each type of roof
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Seams and penetrations are typical breach points.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers, depending on the build-up.
How we price electronic leak detection
We confirm the price for your survey before booking. This is what makes a difference:
- The number of roofs, including extensions and garages
- The use of thermal imaging or a drone
- The size of the roof
- Height and safe access
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
What we need to know
If you can, have these to hand when you get in touch:
- What’s prompted the survey
- The type of building and roof, such as pitched or flat
- Pictures from the garden or a window, if you have them
- When you need the report by
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or email us with the address and the days you’d prefer.
Flat roofs in Lower Kingswood
Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you look after a shop, office or commercial unit, for example near The Belfry, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Anyone responsible for a site like Kingswood Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What this survey cannot tell you

- The extent of water in the insulation
- Areas we can’t reach or that can’t be tested

Lower Kingswood: your questions answered
Will you come out to Lower Kingswood?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
Do you carry out roof surveys in Lower Kingswood?
We do. The survey and report are the same in Lower Kingswood as anywhere else, and visits run on weekdays and weekends.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are often shared, so the building owner or managing agent needs to agree access. We can only inspect what we’re given access to.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show.
Can I check my roof myself?
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
What we do, step by step
Safety comes first on every visit. We inspect what can be seen safely, and if part of the roof cannot be seen, the report says so. Most visits take a length of time set by the membrane area and the build-up, which we set out in the quote. Rural addresses near Lower Kingswood can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Note where any stains or damp appear
- Agree roof access with the managing agent if it’s shared
- Keep pets inside or away from the areas we’re looking at
